Objective To investigate the changes in bone age, and the correlation between the changes in structure and function of cardiovascular and bone age index in children with left to right shunt congenital heart disease (CHD) such as atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). Methods One hundred and thirty children diagnosed CHD had been enrolled, including 52 cases of ASD, 46 cases of VSD and 32 cases of PDA. The cardiac structure and function indicators had been detected by ultrasonic. The anteroposterior iflm of left hand and wrist had been taken. The bone age had been assessed according to“China children bone age score”atlas, and the bone age index (BAI) had been calculated. The differences of bone age among each group had been compared. The linear correlation of the cardiac structure and function indicators with BAI had been analyzed. Results The BAI was statistically different among ASD, VSD and PDA groups (P<0.05). The BAI of PDA group was higher than those of ASD and VSD groups (all P<0.05). The BAI was also statistically different among the groups with different pulmonary artery pressures (P=0.000). The BAI was higher in small defect size group than that in large defect size group (P=0.002). The defect size was negatively correlated with BAI in both ASD and VSD groups (r=-0.48, -0.54, all P<0.05), The pulmonary artery systolic pressure and pulmonary-to-systemic blood lfow ratio (QP/QS) were negatively correlated with BAI in ASD, VSD and PDA groups (r=-0.64--0.38,all P<0.05). Conclusion The bone age and BAI of children with left to right shunt CHD are signiifcantly lower than those of healthy children of the same age . The extent of bone age delay is related with PASP, defect size and shunt volume in children with left to right shunt CHD.

The pharmaceutical properties, including the physical and chemical properties, and the bioavailability are greatly influenced by their polymorphism. In this paper the polymer heteronuclei were used to produce the gabapentin polymorphs that were characterized by X-ray powder diffraction, FT-IR and DSC. The results indicated that the polymer heteronuclei are an effective method to control and select the gabapentin polymorphism. One new polymorph of gabapentin was found besides all known gabapentin polymorphs.

Objective To investigate the changes in physique and the bone age,and the correlation between the changes in cardiac structure and function and the bone age index (BAI) in atrial septal defect (ASD) children.Methods The experimental group included 48 cases of ASD patients,and 30 cases of healthy children were assigned as the control group;the children of both groups were measured for height and weight.Philips ie33 ultrasonic detector was used to detect the indicators of cardiac structure and function,and Philips digital X-ray machine was used to radiograph the left hand and the wrist.Then the bone age was assessed in order to calculate the BAI.Fourteen cases of ASD patients who underwent repairing surgery were measured for orifice area in surgery.The differences in physique and the bone age between the 2 groups were analyzed,and Pearson correlation analysis method was used to observe the correlation between the cardiac structure and function indicators,defect area and BAI in the experimental group.Results There was no significant difference in the age,height,bone age (t =-0.02,-1.31,-1.69,all P ＞ 0.05),while the weight and BAI were significantly different between the 2 groups (t =-2.28,-9.06,all P ＜ 0.05).The height,weight and BAI were significantly different in different pulmonary artery systolic pressure (PASP) patients (F =27.630,23.537,16.704,all P ＜ 0.01),while the age and weight had no difference (t =-1.218,-0.046,all P ＞ 0.05).The height and BAI were significantly different in patients with different defect size(t =2.561,2.191,all P ＜ 0.05).There was no correlation between the age and the BAI in children with ASD(r =-0.175,P ＞ 0.05).The defect size,defect size/atrial septal stretched diameter,PASP were all negatively correlated with BAI (r =-0.349,P ＜ 0.05 ; r =-0.412,P ＜0.01 ;r =-0.539,P ＜0.01).The defect area was positively related to the defect size in 14 cases of children with ASD underwent surgery (r =0.599,P ＜ 0.05),and the defect area was negatively correlated with BAI (r =-0.655,P ＜ 0.05).Conclusions The physical development in ASD patients evidently lagged behind the healthy children,particularly for weight.The BAI of ASD patients is significantly smaller than that of the healthy children,in other words,the growing speed of bone in ASD patients is significantly slower than that of the healthy children at the same age.The lagging extent of physical development and the bone age are related to the PASP and defect size.PASP has more influence on the height,yet the defect size has influence on height and weight of ASD children.There is no correlation between physical development and the bone age with the course of disease.

BACKGROUND:Orthodontic treatment is a mechanical force for tooth to cause the remodeling of periodontal tissue, produced by the tooth movement. The main aspect of orthodontic periodontal tissue remodeling is the alveolar bone. Insulin-like growth factor is an important factor in the remodeling of periodontal tissue, which plays an important role in the growth, differentiation and growth of the cels. OBJECTIVE:To review the role of insulin-like growth factors in periodontal tissue remodeling. METHODS: A computer-based retrieval of PubMed, CNKI and Guizhou Province Digital Library Database was performed to search articles related to the role of insulin-like growth factors in periodontal tissue remodeling. The keywords were “insulin-like growth factor; periodontal tissue; remodeling” in English and Chinese, respectively. RESULTS AND CONCLUSION: Insulin like growth factor belongs to the insulin family, a kind of peptides, which can promote the migration, proliferation, differentiation, colagen and matrix synthesis and alkaline phosphatase activity of osteoblasts, fibroblasts and mesenchymal cels in the periodontal ligament. It also plays an important role in the repair of injury. During orthodontic treatment, the use of suitable orthodontic force combined with insulin-like growth factor can promote periodontal tissue remodeling, accelerate the orthodontic tooth movement and shorten the treatment time for patients.

Objective To investigate the features of the mixed epithelial and stromal tumor of kidney (MESTK) and cystic nephroma (CN) on multi-detector CT (MDCT), in order to improve the accuracy of preoperative diagnosis and differential diagnosis. Methods Based on blind-retrospective review, CT features of 6 MESTK patients and 6 CN patients were reviewed retrospectively, and compared with pathological results postoperatively. Results All the lesions were single regular multi-cystic masses. Five patients with MESTK were diagnosed as Bosniak Ⅲ and 1 as Bosniak Ⅳ. In contrast, 6 of CN were all diagnosed as Bosniak Ⅱ. Six MESTK lesions were all consisted of irregular mixture of solid and cystic components, and the average thickness of septa was 0.93 cm. Six CN lesions were entirely cystic masses without solid components, and the average thickness of septa was 0.23 cm. After contrast enhancement, the solid components of MESTK and the cystic wall of CN presented mild-to-moderate delayed enhancement. Conclusion Some signs on multi-detector CT can help to differentiate MESTK and CN, especially the presence of solid components of the tumor.

Objective To investigate the relationship between the average amplitude of swallowing-related muscles during pharyngeal swallowing and age and swallow model of healthy adults in different age groups.Methods A total of 200 healthy adults were recruited and divided into 4 age groups:group A (18 ～ 30 years old,n =59),group B (30～50 years old,n=50),group C (50 ～70 years old,n=49) and group D (70 years old,n=40).Surface electromyography was used to acquired the average amplitude of electrical activity of the muscles during three swallow models:resting state,voluntary single swallows of saliva (dry swallowing),voluntary single swallows of 5 ml water at once(wet swallowing)and voluntary single swallows 20 ml water at once.The mean value of the average amplitude of normal adults of different ages were calculated and analyzed.Results ①Intergroup comparison showed no difference in the average amplitude of submental muscles and infrahyoid muscles among the 4 age groups (P ＞ 0.05) in all the three swallowing models ;②Intra-group comparison showed that,there were no statistical differences in the average amplitude of submental muscles among the three swallow models between groups A and B (P ＞ 0.05).In group C,there were no statistical differences between dry swallowing and wet swallowing of 5 ml of water in terms of the average amplitude of submental muscles and infrahyoid muscles during dry swallowing.(P ＞ 0.05),however,but there existed statistical differences in terms of the average amplitude of submental muscles and infrahyoid muscles,when comparing dry swallowing with voluntary single swallowing 20 ml water at once(P ＜ 0.05).The average amplitude of submental muscles and infrahyoid muscles during swallowing of 20 ml water were significantly higher than that during wet swallowing(P ＜0.05).In group D,there was no difference between drying swallow and wet swallowing(P ＞ 0.05)in terms of the mean sEMG amplitude of the muscles,but all lower than swallowing 20 ml of water,with a statistically significant differences(P ＜ 0.05).Conclusions The sEMG amplitude in swallowing-related muscles during pharyngeal swallowing is not related to age,but swallowing models.

Objective To explore the feature of epileptiform discharges during day and night in patients with sleep epilepsy and its diagnosis value. Methods Ambulatory EEG (AEEG) was performed continuously for 24 hours in 91 patients with sleep epilepsy. The frequency of epileptiform discharges in wake phase and sleep phase were analyzed. Results Epileptiform discharges were observed in 71 patients. 4 patients showed epileptiform discharges only in wakefulness, 41 only in sleep and 26 both in wakefulness and sleep. 34 patients showed epileptiform discharges only in stage 1 and 2 of NREM sleep, and 33 patients displayed epileptiform discharges in whole cycle of sleep. Seizure frequency in the patients with epileptiform discharges in wakefulness was higher than those without epileptiform discharges or with epileptiform discharges in sleep (both P
